Cetak penyata jumlah yang berjaya pada penyata if

Kandungan soalan

Saya membuat program atm di java. Secara keseluruhan, ia berfungsi. Walau bagaimanapun, saya cuba untuk mencetaknya "Anda telah melebihi had" apabila pengguna memasukkan jumlah simpanan dan semakan yang berjaya. Saya menggunakan pernyataan if untuk melakukan ini. Walau bagaimanapun, saya tidak pasti sama ada ia boleh menjana cetakan "Anda telah melebihi had". Saya baru belajar java jadi harap bersabar.

package atm;

import java.util.Scanner;

public class atm {

    public static void main(String[] args) {
        
        Scanner cin = new Scanner(System.in);
        
        int checking = 1000, savings = 5000, withdrawal = 0, deposit = 0;
        
        System.out.println("======================");
        
        System.out.println("Welcome to Sound Bank!");
        
        System.out.println("======================");
        
        while (true) {
        
        System.out.println("Please select which options: \n (C)Checking Balance \n (S)Savings");
        
        String choice1 = cin.nextLine(); 
        
        System.out.println("Please select of the following: ");
        
        System.out.println("(D)Deposit \n (W)Withdrawal \n (B)Check Balance \n (E)Exit");

Jawapan betul

Soalannya tidak begitu jelas. Tetapi saya menganggap masalah anda telah selesai

double w2 = cin.nextDouble();

double Total3 = cin.nextDouble();

digantikan dengan

double w2 = cin.nextDouble();

double Total3 = 节省 - w2;

Ia sepatutnya berfungsi seperti yang diharapkan.
